Where are the places these minerals are found: Gold, Limestone and kaiolin.
Explanation:
Gold: The Kolar Gold Fields in Kolar used to be one of the major producers of gold in India, before it shut down. Presently the gold mines of Hutti and Raichur produce almost 84 per cent of the country’s gold. The other major centers of gold mining are Dharwad and Chitradurga. The gold mines produce about 3,000 kg’s of gold per annum. The district of Raichur is also famous for its silver deposits.
Limestone: It is another important mineral with an estimated 51,000 million tons. Karnataka has the largest limestone reserve in India. The districts of Gulbarga, Bagalkot, Belgaum, Shimoga and other Uttara Kannada districts are endowed with extensive high grade limestone. The present and consistent production of approximately 14 million tonnes provides for the cement plants in these districts.
China clay (kaolin) consisting dominantly of kaolinite is one of the most sophisticated industrial minerals with a host of applications, viz., in ceramics, refractories, paper coating, filler for rubber, insecticides, cement, paint, textiles, fertilizers and others including abrasives, asbestos products, fibreglass, chemicals, cosmetics, pharmaceuticals, electrical ware, foundry and glass.
The Department of Mining and Geology through their past investigation campaigns in parts of Kerala,identified two major china clay zones viz., the southern china clay zone between Thiruvananthapuram and Kundara (Thiruvananthapuram and Kollam districts) and the northern china clay zone between Kannapuram Madayi -Cheruthazham in Kannur district to Nileswarm - Manjeshwaram in Kasargod district. An estimated reserve of 172 million tonnes (probable reserve of 80 million tonnes and possible reserve of 92 million tonnes) of china clay of sedimentary and residual origin has been arrived at.
Kerala china clay is one of the finest quality clay and is world class. In fact, Kaolin marketed by English Indian Clays Ltd. (EICL), Thiruvananthapuram claims to have similar or even better properties compared to imported clays.

Write the steps for calculating molar mass.
Answer:
Explanation:
1) Find number of each of the type of atom that is present in the compound, using the chemical formula .
2) Then multiply number of atoms of each element that is present in the compound with the atomic weight of each of the element
3) Add everything together and add the units (grams/mole ) after the number
Let finds that of water
Chemical formula of water is (H20 )
hydogens atoms= 2
oxygen atom= 1
Atomic weight for Hydrogen= 1
Atomic weight for Oxygen= 16
Total number of atoms of Hydrogen from the formula (H2O)= 2
Total number of atoms of Oxygen from the formula (H2O)= 1
the molar mass=
Hydrogen: ( 2 x 1)= 2
Oxygen: ( 1 x 16)= 16
Add together= (16+2)
= 18
Then add the unit, we have(18 g/mol.)

Explain about exothermic reaction?An exothermic reaction is one in which energy is given off as heat or light. In contrast to an endothermic reaction, which draws energy from its surroundings, an exothermic reaction transfers energy into the environment.Calcite in marble and limestone dissolves when sulfurous, sulfuric, and nitric acids in polluted air and rain react with it. We observe roughened surfaces, the removal of material, and the loss of carved details in exposed areas of buildings and statues.Because of its basic nature, the calcium carbonate in marble neutralizes the hydrochloric acid in the reaction described above. A base is defined as "a compound that reacts with an aqueous solution of an acid to produce a water and salt solution in which the salt gets separated into its component ions." Any extra salt that remains after a given salt solute has saturated the aqueous solution precipitates out of the solution.To learn more about exothermic reaction refer to :

How can the properties of acids and bases be used to classify solutions?
Answer:
Acids and bases aqueous solutions will conduct electricity because they contain dissolved ions. Therefore acids and bases are electrolytes. strong acids and bases will be electrolytes. weak acids and bases will be weak electrolytes.
What causes the release of energy in an exothermic reaction? Bonds breaking Bonds breaking A catalyst A catalyst Bonds being formed Bonds being formed Electrons escaping the bond
Answer:
weak bonds break and strong bonds form
Explanation:
An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.
Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.
Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.

A study was conducted to see if increasing the substrate concentration has an appreciable effect on the velocity of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was run 15 times, with an average velocity of 7.5 micromoles per 30 minutes and a standard deviation of 1.5. With a substrate concentration of 2.0 moles per liter, 12 runs were made, yielding an average velocity of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason to believe that this increase in substrate concentration causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes
Answer:
There is not enough evidence
Explanation:
For 1.5 moles substrate concentration per liter
Reaction ( n2 ) = 15 runs
average velocity ( x2 ) = 7.5 micromoles per 30 minutes
standard deviation ( s2 ) = 1.5
For 2.0 moles substrate concentration per liter
Reaction( n1 ) = 12 runs
average velocity ( x1 ) = 8.8 micromoles per 30 minutes
standard deviation ( s1 ) = 1.2
Show Reason to believe that this increase in substrate conc causes an increase in mean velocity
Hypothesis test
H0 : μ1 - μ2 = 0.5
H1 : μ1 - μ2 > 0.5
level of significance ( ∝ ) = 0.01
attached below is a detailed solution to the problem
P-value ( 0.073 ) > level of significance ( 0.01 ) hence we fail to reject the null hypothesis
hence there in not enough evidence to believe that this increase causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes

Which of the following answers below is the correctly balanced half-reaction for the reduction of the SO4 ^-2 ion in acid solution? The answer is C, but I don’t understand why. Thanks in advance :-)
Answer:
C
Explanation:
The oxidation number of Sulphur in SO4^2- is;
x + 4(-2) = -2
x - 8 = -2
x = -2 + 8
x = 6
Now,
the oxidation number of sulphur in H2SO3 is
2 (1) + x + 3(-2) = 0
2 + x -6 = 0
-4 + x = 0
x = 4
Hence, the oxidation number of sulphur changed from +6 to +4 which signifies gain of two electrons as shown in option C.
